ABSTRACT:
An actuating installation for working medium valves in reciprocating engines with at least one cam shaft and one cam each for each valve and with at least an indirect actuation of the valves by the corresponding cam, and with hydraulic play-compensating elements, each of which is provided with one working space filled with lubricating oil that is connected to the oil circulatory system of the reciprocating piston engine; the place of the hydraulic connection of the play-compensating elements with the oil lubricating system is located at such a place in this circulatory system, at which the oil circulatory system has a pressure, conditioned on the system, which at all operating conditions lies below the feed pressure of the circulation but above the atmospheric air pressure of the reciprocating engine.
